Tire age and Retreads: two videos going through some data.

[djdalfaro]

Ross, I love your videos. You and I appear to challenge readily available statements similarly. I too went on a hunt for tire date safety info a couple years ago when I bought 6 new old stock tires (stored inside) for $250 to put on my bus. After I picked them up I realized they were 10 years old, and that sent me on the hunt. I too did not find any definitive info, and plan to install them on my bus in the next 6 months or so (at least the 4 drive tires). Thanks for the humor.

There are times I get busy and don't check in on Skoolie.net for a while. This is a reminder of why it is so important to do so, even when I have nothing in particular to learn or share. Up pops a gem. Thanks Ross!

 

[rossvtaylor]

Thanks to both of you, Alf and PB for the support and kind words. Thank you notes sent to each of you, too.

Ross, Yvan shared your videos on Facebook, great videos. I had also looked up the CFR on tires a while ago and found as you did. It is so nice to see factual research, I get so tired of the bs many take as fact. Thanks!

Good videos and study, thanks for putting those together.
Everybody has a different tolerance for risk so I think tire age usage/opinion is often based on one’s risk tolerance. Personally I have a high risk tolerance and don’t have a problem using old tires. I had 20 year old retreads and one blew a few years ago. I still won’t put retreads on the front.

I’m still not totally convinced retreads have the same failure rate as virgin tires. Maybe if there was more studies showing that. My dad was in the truck tire industry for over 40 years and ran a retread plant says this:
No we didn’t use age as an indicator, it was all based on the condition of the casing. In a perfect world retreads are just as good as original tread tires. It all comes down to human error in the retreading process, use to be that way with new tires also before computers took over making them. The retread is only as good as the person handling the process.

Ross, Thank you for all the things you do for the community, from creating fact based informative content and videos to saving folks that have been swindled by others! For me, those people commenting on FB serve only as a stark comparison point to what a reasonable genuine down to earth treasure you are.
Just sayin' :Thanx:

Anyway I've been looking into replacing my tires and found your video very informative.

I'd say that the number 1 factor in tire failure is improper inflation. And yet, most people hardly look at their tires until they have a failure.

I've also about given up on fb, at least for skoolie groups. Between people trying to sell gutted maxxforce 7's for $20k and people pushing crappy products as sponsors (almost as bad as youtube) there is no knowledge sharing or legitimate debate on fb.

I dropped that dumping grounds over 6 years ago. When the persecution of facts, data, and opinons that didn't support the woke agenda became blatant. Having a differing opinion is one thing, silencing the opposing view is intolerable.

I still have my FB account but rarely use it. I’m not sure why anyone would want to use a platform that filters what you say and filters what you see. You don’t know what’s really going on out there when they do that.

Rather than guess, I called the Goodyear tech line after being told constantly that it was imperative to replace tires at the ten year mark. They put me through to the engineering department and I was told in some detail about tire construction and expected lifespan. The engineer said that the ten year rule came about because manufacturers stop collecting data on a new tire at around the ten year mark, and that while they (Goodyear at least) are confident that the internal structure of the tires was reliable for ten years, they have no further data, and tires must be cut apart to inspect them for signs of failure. So they may well last longer but they cannot say because they do not know.

I don’t think they want to know if they’ll last longer.

I agree, there's no money in that...at all. My steer tires are big Uniroyals, I believe, and they just look pricey.

Well there is cord flexing, depending on air pressure, possible steel wire fatigue. Many problems can not seen from the outside. Maybe real quality minded rethreaders do an x ray or other ndt on the tires before they start there process.
I have Michelin tires under my Citroen DS that are now 30 years old and show no sign of cracks.
I have some original tires on my 1962 unimog 404 that show some marginal sidewall cracking.
And then I have 5 year old car tires that show side wall cracking every where.
It seems rubber is not the same.
As Bon Voyage said before, how risk tolerant are you. And how good of a re-thread shop is it.

From personal experience...
When a retread disintegrates it will absolutely destroy the wheel well, brake lines, and whatever else it beats to death on the way out. Don't do it.

This applies to any tire which comes apart. If a tire blows out at speed, it's going to cause damage for sure

This why our wheel wells will NOT be cut down and the one that will have the co-pilot seat over it will have a steel framework to ensure the occupant is protected.
